This ton relates to dating stamps, and is an. improvement upon the construction shown in patents ited to said linnn Annen l). dosi-iv and particularly upon that 'dated ov. 9,

@ne feature .of the impro-vein relates to the re fersible ribbon mech;` ism, nn bracing; ratchets upon the ribbon spools, parvis actuating, said ratonets adapted to be thrown into and ont et action alternately'by reversingF disks conn ed together by a rod ivorling transversely through the housing; of the .i ump, the disks being1 .locked in their two positions by a springI pin entering sockets in the side tace of one of the disks. The disf s each carr).7 a projf .ng tooth adapted to ln one ot the ratchet actuating panfls trom ectino position, and when .the dY s are reversed oy givin them a partial turn on their ases, they iii ne of i paWls ont oi action and loner the other intov action. "lhe penis are supported each upon one of duplicate levers arranged transechanisni and united toi @other at the er ci the machine and to a rei-tical rod ;.l.,bciiniii, troni and pivot-ally ettached to the:` platen arm.

n"ndinal vertical section and are sections and r l 5 are sect! respectively l`igr.

.in sai 7, represent the base or mainirsn he machine, a bensi-,n ci. i ribbon spco lille platen n carried on the snpptcitcd -with a hne ingr lilik a lifting spring' l2 adapted to maintain itin the raised position. lt also carries a knife' tion of the stamp. IThe pawls aresupported upon levers 33 which are duplicates ot each other and extend transversely in opposite directions trom the center ot the ma# chine. The levers are united to each other at their meeting ends and are also pivotally united. 'to the vertical bar 34 which is supported by a pin 35 from a depending projection 56 attached to the underside of the striking arm l0. But. one of the paWls Si? operates its ratchet at any one time and this is due to the fact that they are controlled as to their operative position as follows: Upon the axes of the ratchets 3l and adjacent to each oi them is a disk 37 vvhich disks may appropriately be called reversing disks. Each disk is provided with a :flange 38, a portion of which is cut and is bent outward so as to torni a lifting linger 39, each adapted to move under and liit one of the pawls 32. The disks are connected together by a yoke or bar 4-0 extending transversely' from one. to the other and compelling them to move in harmony and to the same extent. An operating; handle 41 is inserted in the Piange of one of the disks ant. serves as. a means of imparting a partial turn to them.

By cutting away the flange of 'the disks as described he is enabled to give the actuating' parvis and also the holding pawls l2 which are pivoted to a stationary part oft 'the housing as shown, access to their rcspective ratcl'iets so, that the latter can be operated. The lifting fingers 39 not only hold the actuating pawls 'out of action, but they also act to prevent wear upon the points of those pawls by rubbing on the nncnt. portions of the flanges during the move ments received While they are in their nonacting position. The uncut portions of the flanges also support the holding paWls during the periods of non-action. When the disk carrying the handle is operated to reverse the ribbon, the movement carries a lifting linger' unfler one of the actuating paWls and a ortion of the uncut iiange under the holdlng pawl. at the same side of the machine with the actuating pawl and the same movement allows the actuating and the holding paWls at they opposite side of the machine to drop into actmg position on their ratchet. In other Words, a partial turn'of the reversing disks lifts the paWls at one side out of action and at the same.

time drops the two paWls at the other side into action. To lock the reversing disks in their two positions .he provides a spring pressed pin 60 movable toward one of the disks and sockets-61 in the side face of the dlsk adapted to receive said pin. It will be understood that with each stroke imparted to the press a feeding movement of the ribbon W'ill take place and the mecha-A nism described permits a very easy reversal of the feeding mechanism.

vThe advantage of a reversible feed such as that shown is that it secures an equal Wear or use of the ribbon Whereas With the usual form of ribbon Winding automatically only one Way the passage of the rib'- bon over the plate and date characters increases -in speed as it is Wound on one spool. Being so easily reversible, he avoids excess of the ribbon on either spool and adds greatly to the life of the ribbon besides securing more uniform impressions.

I claim as the invention of said ALEX- ANDER D. JosLiN the following l.' The combination with printing type characters of an ink ribbon movable transversely of said charactersfspools supporting said ribbon and located one at each side of the printing characters, a pivoted housing supporting said spools, ratchets and pavvls for operating the spools, reversing disks controlling the pawls so that only one of them acts at a time, transverse levers carrying the pawls, and a striking arm mechanically united to said levers and operating them at each dating operation.

2. The combination With printing type characters of an ink ribbon movable transversely of said characters, spools supportcharacters of an ink ribbon movable trfnsversely of said characters, spools supporting said ribbon and located one at each side of the printing characters, a pivoted housing supporting said spools, ratchets and pawls for operating the spools, oppositely extending levers supportlng said pawls, means for reversing the ribbon feed, and a striking arm connected to and operating said levers.

4. The combination with printing type characters of an ink ribbon movable transs versely of said characters, spools supporting said ribbon and located one at each side of the printing characters, a pivoted housing supporting said spools, ratchets and pawls for operating the spools, oppositely extending levers supporting said pawls, re-` versing disks controlling the pawls and mounted on the axes of the ratchets, and a striking 'arm connected to and operating said levers.
